Flooring material of the present invention that can achieve the above object is a multi-layered flooring material which is laminated with a lower layer, a base material layer, an upper layer, a printing layer, a transparent upper layer and a UV layer, the particle size of 5 ~ 20μ in the lower layer or transparent upper layer of the flooring material. 1 to 30 parts by weight of jade powder is added so that far-infrared emissivity is 0.9 or more.

The jade used in the present invention contains an ingredient beneficial to the human body, which is recently used as a functional product to improve health, and has an excellent far-infrared radiation efficiency when compared with ganbanite, ocher, ceramic, and charcoal that emits far infrared rays or anions. The main components are 40 to 50% by weight of SiO ₂ , 10 to 15% by weight of H ₂ O, about 0.2% by weight of Fe ₂ O ₃ , about 5.0% by weight of CaO, 25 to 45% by weight of MgO, about 0.15% by weight of Cu. %, About 0.05% by weight of Co, about 0.1% by weight of Mn, and about 0.01% by weight of Zn.

Having such a jade in the body not only activates blood circulation and physiological functions, but it is also known to have effects such as sweating, pain relief, pain relief, and the discharge of waste products in the body. Recently, mats, bedding, cosmetics, Although it has been applied to saunas, bathrooms, clothing, portable goods, ceramics, accessories, and ornaments, it has not been applied to architectural interior materials where people spend most of their time. To this end, a means for producing and supplying building interior materials by adding a large amount of jade is required.

Jade used in the present invention is nephrite jade, white nephrite, jadeite or jadeite, and 1 to 30 parts by weight of jade powder having a particle size of 5 to 20 µ was applied to the lower layer or the transparent upper layer of the flooring constituent layer. .

If the particle size of jade powder is less than 5μ, the viscosity of the sol containing jade powder becomes high, which makes it difficult to process, causing problems in processability, and when the particle size of jade powder exceeds 20μ, there is a problem in the surface of the product because of the large particle size during coating. There is a risk of precipitation in the sol phase.

In addition, when jade is used less than 1 part by weight, the effects of antibacterial, deodorization, anion radiation, far-infrared radiation, etc. do not occur when jade is added, and when used in excess of 30 parts by weight, poor workability occurs.

According to the present invention, by applying the finely divided jade powder, the surface area of jade is significantly increased, and even if a small amount is used, the effect of jade is excellent, and even if added to a transparent layer such as a surface layer, the effect can be exerted without deterioration of transparency.

For example, in the flooring of the present invention, a foamed layer or a non-foamed printed layer 2 is laminated on a base layer 1 to form a printed pattern 3 such as a rotary screen and gravure, and a transparent upper layer 4 thereon. After forming a rotary screen printing layer (5) in which the natural jade is put on the printed semi-finished product and laminating the transparent upper layer, the transparent sol (SOL) or sheet in which the pulverized natural jade is added in the range that does not affect the transparency 7) by laminating a thin layer on the transparent upper layer, it is possible to stack jade to emit far infrared rays in the region closest to the human body, so that the intrinsic function of jade such as thermal effect and antibacterial, deodorizing effect or metabolism promotion of far infrared rays It can be delivered effectively.
